Encoding the key of a 2007 Renault Kangoo

This car began failing a key then when it no longer turned on was tested with the other and the other if it worked then 6 months later this other failed and the owner was doing it was when putting the contact squeezed the remote control button and thus already turned off the witness light but now 2 months later it no longer works at all and no DTC comes out. The Scaner has a function to test the lines of the Inger and says that all the lines that there is perfect communication between the immobile and the ECU I have sent you several MP asking you some very specific questions close to the "table" does it really exist? Thanks for answering

I already throw a DTC "Transponder signal under" only that says the scanner maybe this is something this

Have you tried to erase the breakdown?

The injection calculator does not have any reference code in memory: the sent code is recorded in the memory. If there is no coincidence of the Central Codes/Central Unit of the cabin, the system remains blocked. The
red antiarranque witness flickering (rapid intermittency). The start of the vehicle is not authorized

Non -used antiarranque1 cap.2 mass. 3+ before contact. 4 Signal output (they are the cap pins that are in the clausor chasm)
